Community Trust ScoreLikely Real
One-third of Ethereum nodes operate on American soil. This figure, revealed in a study by the Cambridge Center for Alternative Finance, is certainly thought-provoking.
What Happened
The Cambridge Center for Alternative Finance mapped the geographical distribution of Ethereum nodes. The result: about one-third are located in the United States. The rest are primarily spread across North America and Europe. Two blocs, two continents, and a large part of the world almost absent from the equation. It’s not exactly what one would call a decentralized network in the strictest sense. In the post-merge context — Ethereum’s transition to proof-of-stake — this geographical concentration takes on added significance, as the question of nodes’ energy consumption remains open depending on where they are physically hosted.
No details on the exact methodology from the Cambridge Center in the source. But the figure of one-third is telling enough.
Historical Context
We’ve seen this story before. In 2018, Bitcoin faced a similar issue: a massive concentration of miners in China. At the time, the same questions about resilience and regulation were circulating. Then in 2021, Beijing banned mining overnight. Thousands of machines had to migrate within weeks — to Kazakhstan, the United States, Eastern Europe. The forced relocation was chaotic, and the Bitcoin network temporarily dropped in hashrate before stabilizing. This clearly illustrates the concrete risk of over-reliance on a single jurisdiction.
There’s also the EOS episode in 2019. Node voting highlighted vulnerabilities linked to excessive control concentration, forcing reforms in the protocol’s governance. Different from Ethereum, but the same logic: too much power concentrated somewhere, and the system becomes fragile.
These two precedents show that decentralization is not just a marketing argument. It’s a matter of operational survival for a network that wants to remain credible in the long term.
Why It Matters
The American predominance creates several problems simultaneously. The first, and probably the most immediate: regulatory risk. If Washington tightens the legal framework around blockchain infrastructures — and signals have been mixed for years — a disproportionate part of the Ethereum network is directly exposed. One law, one administrative decision, and a third of the nodes could find themselves in a legal gray area.
The second problem: the promise of decentralization. Ethereum was built on the idea of a network that no one truly controls. But if one country hosts a third of the nodes, this promise becomes difficult to keep. American regulators would theoretically have disproportionate influence over the network’s operation — not necessarily through direct intention, but by sheer geographic weight. And other jurisdictions see this very clearly.
The third point, less obvious but real: resilience to local disruptions. A natural disaster, a major power outage, a sudden political decision — if it affects the United States, a third of the network wavers. A more uniform distribution would better absorb such shocks.
Then there’s the energy question. The transition to proof-of-stake was supposed to drastically reduce Ethereum’s carbon footprint. But if the majority of nodes operate in regions where electricity mainly comes from fossil fuels, the environmental benefits of the merge are partially negated. Ethereum’s green argument holds less weight when considering where the energy powering the validators comes from.
What to Watch
Three indicators to keep in mind. First, the percentage of nodes relocated outside the United States: if this figure falls below 25%, it would mean the trend is truly reversing. Next, the number of new American regulations targeting blockchain infrastructures — an increase could paradoxically accelerate centralization, as well-established operators in the U.S. will have more resources to comply than smaller players. Finally, the network’s energy consumption over a rolling six-month period: significant variations could influence node location decisions, especially if some American states tighten their energy policies.
The issue of digital sovereignty is also present, in the background. Other countries might want to attract these infrastructures to their own territories — or, conversely, regulate them more aggressively. This potential movement could further fragment the node map, but not necessarily in a positive way.

In short, Ethereum faces a structural tension between what it is supposed to be — a truly distributed network — and what it is in practice: a system where a third of the physical infrastructure depends on a single jurisdiction. The network’s performance, latency, and ability to balance load among validators all suffer from uneven distribution. One-third of the nodes in the United States, that’s the figure from the Cambridge Center for Alternative Finance.
